If you wish to find the Lowest Common Multiple (LCM) or Greatest Common Divisor (GCD) in Excel, this post will be helpful. We have covered both scenarios.

Polynomial GCD: The computation of the greatest common divisor among polynomials, often in an approximate sense when coefficients are subject to inaccuracies.

Eckford Cohen, Arithmetical Functions of a Greatest Common Divisor. I, Proceedings of the American Mathematical Society, Vol. 11, No. 2 (Apr., 1960), pp. 164-171 ...

We show that if two monic polynomials with integer coefficients have a square-free resultant, then all positive divisors of the resultant arise as the greatest common divisor of the values of the two ...
